I guess it could lose some strength if you just bolt the frame back together....my idea was to cut off part of the left side frame to do the stator replacement and then , using some pieces of steel rod or tubing that fit inside the frame tubing, WELD the piece back...Hit it with some black spray paint and your done.Knifemaker I read on another post that someone else thought about it and did that, and someone commented on how the frame was not designed to come apart there and it lost around 80% of the strength within the frame.....
The weld would actually make the that side of the frame stronger than it was before.
I should also point out that the Vulcans frame is likely stronger than it needs to be in the first place. This is not a 150 hp machine. And most folks here don't toss it over and test the rigidity of the frame at high speeds....and those that have likely could not tell the difference.
And the "engineers" that designed the Vulcan were pinheads anyway...because they made the WRONG SIDE of the frame removable. they did this to speed up assembly....NOT to make working on the bike any easier. Poor planning for sure, a mark of bad engineering.
Cutting holes in factory designed engine pieces? Yeah baby.. that's called "customizing". :smiley_th
